Each volume has a subtitle with the suffix "-hen" (編, lit. chapter), similar to the naming of Higurashi no Naku Koro ni arcs. Notably, the chapter names of the first two volumes are pun on the names of flowers as they are exactly the same as the Japanese names of Aster savatieri and Chloranthus japonicus respectively, while the chapter name of the last volume is an idiom including the literal letter "flower" (花).
